<h2 id="details">详细信息</h2>
<p><a href="qml-qtquick-animatedsprite.html">AnimatedSprite</a> provides rendering and control over animations which are provided as multiple frames in the same image file. You can play it at a fixed speed, at the frame rate of your display, or manually advance and control the progress.</p>
<p>Consider the following sprite sheet:</p>
<p class="centerAlign"><img src="images/animatedsprite-loading.png" alt="" /></p><p>It can be divided up into four frames:</p>
<p class="centerAlign"><img src="images/animatedsprite-loading-frames.png" alt="" /></p><p>To play each of these frames at a speed of 500 milliseconds per frame, the following code can be used:</p>
<div class="table"><table class="generic">
 <thead><tr class="qt-style"><th >Code</th><th >Result</th></tr></thead>
<tr valign="top" class="odd"><td ><pre class="cpp">

  AnimatedSprite {
      source: <span class="string">&quot;loading.png&quot;</span>
      frameWidth: <span class="number">64</span>
      frameHeight: <span class="number">64</span>
      frameCount: <span class="number">4</span>
      frameDuration: <span class="number">500</span>
  }

</pre>
</td><td ><p class="centerAlign"><img src="images/animatedsprite-loading-interpolated.gif" alt="" /></p></td></tr>
</table></div>
<p>By default, the frames are interpolated (blended together) to make the animation appear smoother. To disable this, set <a href="qml-qtquick-animatedsprite.html#interpolate-prop">interpolate</a> to <code>false</code>:</p>
<div class="table"><table class="generic">
 <thead><tr class="qt-style"><th >Code</th><th >Result</th></tr></thead>
<tr valign="top" class="odd"><td ><pre class="cpp">

  AnimatedSprite {
      source: <span class="string">&quot;loading.png&quot;</span>
      frameWidth: <span class="number">64</span>
      frameHeight: <span class="number">64</span>
      frameCount: <span class="number">4</span>
      frameDuration: <span class="number">500</span>
      interpolate: <span class="keyword">false</span>
  }

</pre>
</td><td ><p class="centerAlign"><img src="images/animatedsprite-loading.gif" alt="" /></p></td></tr>
</table></div>
<p>To control how <a href="qml-qtquick-animatedsprite.html">AnimatedSprite</a> responds to being scaled, use the <a href="qml-qtquick-item.html#smooth-prop">smooth</a> property.</p>
<p>Note that unlike <a href="qml-qtquick-spritesequence.html">SpriteSequence</a>, the <a href="qml-qtquick-animatedsprite.html">AnimatedSprite</a> type does not use <a href="qml-qtquick-sprite.html">Sprite</a> to define multiple animations, but instead encapsulates a single animation itself.</p>
